基于下垂控制的直流微网多储能系统研究
DC Microgrid Multiple Energy Storage System Research Based on Droop Control
摘要
Abstract
With the development of microgrid and energy storage technology,multiple energy storage in the application of microgrid is more and more widely,however,in the process of discharging,the differences of SOC between the different energy storage units will make part of battery quit running ,this will lead to the decrease of the system stability. For this problem,the SOC—I droop control method to control multiple energy storage units on coordination was put forward,the SOC—I droop control method of the controller was designed by analyzing the relationship between energy storage SOC values and the discharge current I,eventually the controller power of energy storage is coordinated and make the charged state(SOC)of energy storage units consistent,improve the stability of the microgrid system.关键词
